I don't know if there is a special way we can make suggestions to the forum, but I have an idea for a sub-forum that I think would be a good fit and addition to DefensiveCarry.
The sub-forum would be DIY (do it yourself) and intended to cover things like making your own holster, working with kydex, building stuff from scratch (or kits) or other things. I recently posted something regarding kydex and the only close sub-forum was the reference and how-to forum. That forum requires approval, or moderation for something to be posted there.
I am a DIY kinda guy, I much prefer to do things myself if I can. So I hope the mods or whoever controls the forum gives it some thought.
